McKenzie Lowe is battling a rare brain tumor and her family wants her to be able to use a treatment that has not been approved by the Food and Drug Administration.

"It's the only thing that we've talked about with people that have actually live through this and are in their late 20s, 30s and so on. So we know this medication is what she needs, but the FDA won't give it to her," said Frank LaFountain, McKenzie's grandfather.

So the family is collecting signatures to petition the FDA for a compassionate-care exemption

"And she has gone through radiation and she has gone through chemo and we'd like to give this a shot," said Joann LaFountain, McKenzie's grandmother.

"She's a sweet girl and she deserves this. And I don't know how people can say they can't give children this. She needs a chance to live life," Joann LaFountain added.

The petition is posted online in hopes of getting 100,000 signatures. People are responding from around the world.

"So then I can just get the medicine that I need and I'll be better," said McKenzie.
